A F32 code indicates a Long drain as well as LD. If you have checked the discharge hose to make sure of no blockages, Next i would look at the pump itself. I have seen change gather in the pump and create enough of a blockage to keep the water from going out in a timely manner. Lastly Does the water go out in a timely manner? If you are still getting a code, and you know that the pump is good, the impeller blades on the pump are intact, the water is leaving the tub fast. The last and only thing left would be the control which monitors the amount of water in the tub. Very unlikely this is the culprit, but its a possibility. Good luck.

I took the pump apart - seemed OK. Then I took the control panel off, to get to the electronics, and disconnected and reconnected every electrical lead to the electronic components. After reassembling the washer, it worked just fine. It appears to have been a bad electrical connection.

Excellent! You have a pretty easy machine to work on. And for the most part, pretty reliable. Some of the replacement parts are expensive, but all in all, a pretty well built unit. From what you have found, If the problem continues, I would assume the control would be the culprit. I have seen a poor electrical connection at the control which was causing "ghost codes" before. I typically will use a very small amount of contact cleaner, and some Electrical grease to remedy the problem. Good Luck!
